Abstract
This document is a compilation of issues found during six
interoperability events and 5 years of experience with implementing,
testing, and using Stream Control Transmission Protocol (SCTP) along
with the suggested fixes. This document provides deltas to RFC 2960
and is organized in a time-based way. The issues are listed in the
order they were brought up. Because some text is changed several
times, the last delta in the text is the one that should be applied.
In addition to the delta, a description of the problem and the
details of the solution are also provided.
